Viscosity measurement services

Project Description

PTB provides viscosity measurement services to customers from GB:

Supply of Newtonian reference liquids with certified values of dynamic and kinematic viscosity. (Currently about 30 reference liquids with viscosities at 20 C between 1mPas and 700 000 mPas are available)
Calibration of glass capillary viscometers (suspended-level, U-tube and Cannon-Fenske viscometers).


Final Report 2011-05-16

Since 1st of January 1989 the complete measurement service as described below is provided to customers from GB.

1. Supply of Newtonian reference liquids with certified values of dynamic and kinematic viscosity. (Currently about 16 reference liquids with viscosities at 20 °C between 1 and 700 000 mPa s are available.)

2. Calibration of glass capillary viscometers. (Suspended-level, U-tube and Cannon-Fenske viscometers).

The service within this project is closed on 2011-05-15.
